Abstract: Prepn. of bis-(2-ethylhexyl)ether (I) comprises reacting 2-ethylhexen-2-al (II) with 2-ethylhexanol (III) in the presence of an acid catalyst (IV) at 50-200 deg.C, and hydrogenating the resulting diene (V) over a transition or noble metal catalyst. (Where R1 is ethyl and R2 is 2-ethylhexyl). (IV) includes mineral and Lewis acids, e.g. H2SO4, toluene sulphonic acid, phosphoric acid, BF3, ZnCl2, and is used in 0.1-2% w.r.t. (II). Pref. the (II) and.

Abstract: Tetrahydrofuran (I) is polymerised using SbCl5 as catalyst in presence of >=1 carboxylic acid or anhydride in which the SbCl5 is pref. dissolved, allowing a reduction in catalyst concn. The catalyst also contains an alcohol as activator. Catalyst activity is substantially increased, the polymerisation rate and output being approx. doubled.

Abstract: Process for prodn. of cyclic ethers from alpha,omega-diols or mono- or diesters of these made by treatment with an acid, comprises treating the alpha,omega-diol (ester) which is capable of forming a cyclic ehter by splitting off water on an acid, with (a) a dil, hydrogen halide acid or an aq. acid with a dissociation constant in water of >=1.10-6, or with a cpd. which forms such acids in aq. soln., and (b) a salt, whereby either (a) and/or (b) gives halide anions. Simple process giving high yields of cyclic ether with min. by-prod. formation. In a typical process, butanediol-1, 4 is converted into tetrahydrofuran.

Abstract: Hydroxylated polymers, esp. polyetrahydrofuran, for polyurethane prepn. are prepd. by saponifying acyloxylated polymers at 10-200 degrees C in an aq. salt soln. contg. a catalyst consisting of an acid or an acid-forming cpd. (pref. a halo acid). The reaction mixt. may contain an alcohol which is immiscible, or only partly miscible with water. The simple, economic process avoids the use and recovery of special solvents, and leads to less pollution by by-prods.
